Här har vi en mappning av en trimmad Volvo 740 GL (B230F) före och efter optimering:
Fastmoving? @ Svenska Volvo 7/900 Klubbens forum
Som mest 13.5 hk (@ 2000 varv) mer.. osv osv
Visserligen en rätt så ändrad motor, men visar ju att lite småtuning kan ge en del.
Men visst, en originalmotor är väl en annan sak.
Schysst tråd på Turbobricks-forumet om chiptrimning (främst turbo då naturligtvis, sen gäller det väl container-motorer) skriven av en av herrarna som jobbar på Hi Tuning (

"Q: What are the gains?
A: For all chips, better driveability and overall power. It will gain "more area under the curve" so to speak. The chips make the car perform it´s best and that is how it should have been from the factory, but Volvo had to factor in a lot of variables such as negligent mainetance etc. and still make the car work at all. That is why the stock chips lack so much power and driveability.
Q: What is "Stage 0"?
A: It is the basic things you should do to/for your car to keep it in good shape before doing any modifications. This usually means to keep the engine clean inside and out, new/good oil, new/good air filter, running good gas, using new/good spark plugs, using new/good spark plug wires, using new/good distributor, keeping all the electrical connections clean and the wires whole, keeping the mechanical components clean and functioning, using a new/good timing belt, using new/good auxilliary belts etc. Don´t ask me about problems with the chips unless you have "Stage 0" in order.
